Fr, how do you all hold down an in-person job?

I’m 24 and developed symptoms at 20. I did a good chunk of college online and had two remote internships. Remote jobs were impossible to get and my family said I was limiting myself and letting fear control me, so I started an in-person job that I really wanted.

Well, everything was fine until I had a flare-up 3 months in. I’ve had two meetings so far where I’ve been told I look sick and come off as rude when I’m not feeling good. This feedback isn’t something I can really improve as when I am fighting nausea and being unbalanced I can only do so much to appear peppy. Customers also sometimes get annoyed when I ask them to repeat something several times. Not to mention that I’m not very reliable as I can suddenly get vertigo an hour before a shift and have to call out. I already used all of my paid sick days (2) so I don’t see how I can even survive off of an income if I keep having to miss work randomly. And if I go in when I’m unwell, as I did several times, I get negative feedback.
